Figure 15: TN2302AP Media Processor (MedPro) operation
To do the job, the circuit pack has a set of DSP resources. These resources are deployed
dynamically and flexibly to any of a number of tasks, including:
●
Originating and terminating IP-based packet-switched audio streams
●
Establishing and maintaining an RTCP control channel for each IP audio channel
●
Compressing and decompressing audio (for example, G.729 to G.711)
●
Terminating TCP for an incoming T.120 data stream, and transcoding it to H.221-
compliant format for transmission onto the TDM bus and vice-versa
●
Summing multiple audio channels into a composite signal for audio conferencing
The S8700 series Media Server is responsible for sending messages to the circuit pack to
allocate and to configure the DSP resources to the required task and connecting multiple
resources into a chain that performs the desired media processing function. In addition, the
Media Server sends the information to the destination of these audio streams.
